Determining Whether to Apply Signed or Unsigned Patches to Your System

The key factor when determining whether to apply signed or unsigned patches to your system is whether you trust the source of patches.

If you trust the source of patches, for example, a patch CD from a known distributor or an HTTPS connection to a trusted Website, you can use unsigned patches. However, if you do not trust the source, use signed patches.

If you are unsure about whether to trust the source of patches, use signed patches.
